Specification of Letters Patent.

T 0 all whom it may concern:

Be it known that 1, Louis ESSELMANN, a citizen of the United States, residing at the city of St. Louis, in the State of Missouri, have invented certain new and useful Improvements in Pastry-Cone Machines, of which the following is a specification.

T his invention relates to certain new and useful improvements in mold-closing and opening devices for pastry-forming machines. The object of this invention is to provide novel mechanism for automatically closing and locking the molds until the pastry within said molds has been cooked, and then unlocking said molds so that the cooked pastry may be removed therefrom. In the drawings, this invention is shown as applied to a machine for manufacturing pastry ice cream cones, but it must be understood that this invention may be employed equally well on other machines of this type.

In the accompanying drawings forming part oi this specification, in which like numbers of reference denote like parts wherever they occur. 1

Figure 1 is a top plan view 01" an ice cream cone machine showing a practical application of this invention;

. Figure 2 is a iragmental view of the looking device showing a mold in locked position;

Figure 3 is a top plan view of the locking device;

Figure 4 is aside elevation ot the locking device shown applied to an ice cream cone machine;

Figure 5 is a detail of the locking link;

Figure 6 is a tragmental sectional view showing the manner in which the molds are unlocked preparatory to removing the cooked pastry;

Figure 'T-is a top plan view of the unlocking device, and

Figure 8 is a side elevation of the unlocking device shown applied to an ice cream cone machine.

Referring more in detail to the drawings, it will be seen that in carrying out this in vention, a large rotatably mounted gear wheel 1 is employed and upon this large rotatably mounted gear wheel 1 are provided a plurality of pastry molds or pans 2. These pans are of the type used in the manufacture of ice cream cones. Meshing with the gear Wheel 1 is provided. a pinion 3,

which is driven in the direction indicated by the arrow by any suitable means, such as an electric motor (not shown). This will cause rotation of the gear wheel 1 in a clockwise direction. The pans 2 are preferably composed of two members and 5 (see Figure The lower member 5 or each pan 2 is rigidly mounted upon the gear wheel 1, and the upper member i (which may be termed the lid) is pivotally mounted upon the member 5, as at G. This allows the upper memher a to be swung upwardly about the pivot (3 to permit the removal of the cooked pastry.

To raise the lids oil? the molds 2, vertical arms 7 are provided upon the inner ends of the said lids 4. These arms 7' terminate in stud shafts 8, on which are ro tatably mounted rollers 9, which strike against and ride within cam 10. This cam opens the molds 2 in order that the cooked pastry may be re moved and then permits automatic closing of said molds after they have been refilled with the uncooked batter, the lids 1- closing by gravity. The batter is fed into the molds 2 as they pass under a batterd eeding device 11 (described in Patent 1,303,218, dated May 6, 1919). After the lower members 5 of the molds 2 have received their charges of fresh batter, the cam permits the upper members or lids 4 of the molds 2 to drop into par tially closed position, shown at the right in. Figure 1. The molds 2 then pass under a cooking hood 12, in which heat is applied to said molds by any suitable means, such as a gas burner (not shown). anisms for tightly closing and locking the lids d of the molds 2 shortly after the said molds have enteredjthe hood 12, consists of two rotatably mounted disks 13 and let. These disks are rotatably mounted on spaced arbors 15 and 16, said arbors being rigidly mounted on an upstanding bracket -7. Stationary collars 18 prevent any horizontal movement of the disks 13 and 14, along the center lines of their respective arbors 15 and, 16. The outer ends of the mold members at and 5 project to form arms 19 and 20. Upon the upper arm-19 is mounted a friction-reducing roller 21, and upon the lower arm 20 is provided a locking link 22 pivotally mounted at 23. This link 23 is provided at one end with a loop 24 adapted to receive an extension 25 of the arm 19. As the molds rotate, the roller 21 on the arm 19 strikes the periphery of the disk 13 below the center Closing meehiii line of said disk. As the molds 2 continue their travel, the roller 21 travels on the periphery of the disk 13 to its lowermost point,

shown in Figure 2. During this operation, the arm strikes and is supported by the disk 14. This relieves the arm 20 of the strain caused by the downward movement of? thelid t on the mold 2. The arms 19 and 20 are locked in this closed position by the link 22 in a manner hereinafter described.

In order to move the locking links 22 to operative position I have providedan an nular track 26 surrounding the gear wheel 1 and at a slight distance therefrom, as shown in the drawings. l i hen the molds 2 are un locked, the links 2 ride around on the track 26 in an inclined position, as shown in Figure l. Upon this track 26 at the point where the lids 41: ot the molds 2 are completely closed by the disks and Li, the shoulder or projection 2'? forces the top 2% of the locking links 22 over the projection on the arms 19. This effectually locks the lids i of the molds 2 in a closed position. The molds 2 continue on under the hood 12 until the pastry in the pans is thoroughly cooked.

After the pastry is thoroughly cooked, the molds must be unlocked, so that the cooked pastry may be removed therefrom. To accomplish this, the depending wedge-shaped arm 28 earriul by the supporting framework of: the machine, is so placed that the point of said arm 28 :torces its way between the rollers 21 of the arms 19 and. the upper end 24 oi? the links 22, thereby forcing the links 22 off the arms 19 as shown in lligure 7. The unlocked molds 2 then pass on from under the hood and are opened by the cam 10 operating against the rollers 9 of the mold lids 4. The cooked pastry may then be removed by an attendant, and the operation of the machine repeated.

While the preferred embodiment of the invention has been shown and described, it is to be understood that minor changes in the details of construction and arrangement of parts may be resorted to within the scope of what claimed, Without departing t'rom the spirit of the invention.
